<strong>kern_return_t   ledger_return_remote</strong>
                <strong>(ledger_port_t</strong>                           <var>ledger</var>,
                 <strong>host_t</strong>                               <var>host_name</var>,
                 <strong>ledger</strong>                            <var>service_port</var><strong>);</strong>
</pre>
<h3>PARAMETERS</h3>
<dl>
<p>
<dt> <var>ledger</var> 
<dd>
[in ledger send right]
The ledger whose service port is desired.
<p>
<dt> <var>host_name</var> 
<dd>
[in host-name send right]
The name for the host requesting the service 
port.
<p>
<dt> <var>service_port</var> 
<dd>
[out ledger-service send right]
The ledger service port.
</dl>
<h3>DESCRIPTION</h3>
<p>
The <strong>ledger_get_remote</strong> function returns the remote ledger
service port for the 
ledger
<h3>NOTES</h3>
<p>
This interface is not implemented in OSF/1 R1.3.
<p>
This mechanism supports distributed resource ledgers in the following way:
<dl>
<dd>
With <strong>ledger_set_remote</strong>, a ledger is assigned a remote
ledger service port.
<dd>
This ledger is used as the ledger for a create operation.  
If the ledger is local to the target kernel, all is fine.
<dd>
For a non-local creation, the target kernel sees that the supplied
ledger is not 
a local ledger.  The kernel sends a <strong>ledger_get_remote</strong> message to it,
including the host name.
<dd>
The (remote) ledger receives this message, ignores the host name and returns 
the remote ledger service port.
<dd>
Assuming that the remote ledger service port is not a local ledger, the kernel 
sends a <strong>ledger_get_remote</strong> message to this service port.
<dd>
A server receives this request (with the <strong>ledger_return_remote</strong>
server interface) 
and uses the identity of the service port as well as the host name of the 
target kernel to locate or create a suitable ledger on that kernel.
<dd>
The port for a ledger on the target kernel is sent to that kernel and used.
